I went to the museum before and after the renovation.
Before, there was lots of cool stuff, and plenty of memorabilia to keep the Northernjets, Westernjets and Northeasternjets crowd happy. It was a little musty and a little "aviation museum on the side of the road-ish", but not a bad way to kill an hour and a half.
After? They did a fantastic job renovating the hangar. It's a beautiful restoration. But it seems like half the stuff that was in the old museum isn't there. I did the whole thing in 45 minutes flat. It reminded me of visiting the Udvar-Hazy after it first opened. You rattled around that place and could see everything in nothing flat.
I'm hoping this is just a case of filling in the new space with stuff that was put in boxes during the resto. The do have two of the most awesome airplanes ever built sitting outside it what look to be perfect condition. Someone spent some serious coin on it, and it seems like it is shaping up very nicely.
BTW, if you are staying over at the Holiday Inn Mall of America in MSP, you can go visit the NWA History Centre in the basement of the Wings Credit Union next door. It only takes a few minutes, but they have some neat stuff, and you can get a "Hermon the Duck" hat.
